P.S. My boss' reaction on my first sly day was (20 minutes into our meeting) "Did you get new glasses?"
Everyone worries about the size of their forehead. (Clue, it will actually look smaller sly.) Everyone worries about the shape of their head. Everyone worries about showing up for work that first day.All of these worries are for naught and are just stalling tactics.
A bald head is very distinguished. I get that comment frequently.
One question for you: what kind of place is the real estate agency in terms of dress / appearance / clientele? If it tends toward the conservative side, then buzz down gradually. That will give you and your colleagues there some time to adjust to each other. Once you feel comfortable with them, shave smooth. There might be a few comments initially, but they'll pass because they'll know you and know your good work. And remember - strangers coming into the office will not have known you any other way, so there's no "before / after" comment they can make.By the way, we all worry about what our heads will look like bald. Don't worry too much about it - you'll look great. More importantly, you'll adjust quickly to the sly look and feel great about yourself. Sporting a shaved head is incredibly liberating.
